Investigators say he threw a flammable liquid through the window of a Planned Parenthood office in Thousand Oaks on Sept. 30. The office sustained little fire damage but its sprinkler system caused water damage.

Sheriff's Sgt. Dean Worthy says Perez had an ongoing feud with his ex-girlfriend who worked at the office. No one was in the building at the time of the fire.

Perez already was jailed for a series of other criminal accusations, including domestic spousal battery.
